With it, you can “Enable Google Sign-In with only a few lines of code”.
On the client side, a web frontend, whenever a user signs in, a token is generated.
Then, this token is passed on all requests to the backend as a way to authenticate users.
However, I needed to verify the tokens. I couldn’t find anything that suited my needs so I decided to write a small library for that and publish it as a crate.
The code is on Github. I’ve also written a small documentation.
